HIGH HEAT INSULATING FIBER SHEET

摘要

PURPOSE: To obtain a fiber sheet excellent in morphological stability and having both highly heat-insulating properties and air permeability by striatedly dispersing a resin containing ceramics and a metal all over the one side of a web. CONSTITUTION: This fiber sheet is obtained by dispersing and coating a resin 3 on a web 2, permeating and making thickwise striae 4 and forming a resin film not only on the web surface but also in the web and so the sheet has highly heat-insulating properties and >=10 cm<3> /cm<2> .s permeability wherein the web 2 comprises fiber 1 such as cotton or polyester short fiber and the resin 3 is acrylic resin, a styrene/butadiene resin or the like and contains ceramics (e.g. zirconia, silica or alumina having 0.05-10μm particle diameter) or the ceramics and a metal (e.g. aluminum or zinc) and is dispersed and coated 0.5-50 wt.% based on fiber weight of the web by screen method or the like.
